I'll add my own speculation, all the round the clock coverage of events like this by the media seems to be followed by copy cat attacks.
Every time something like this happens, seems like it would be a good idea for schools, etc to be on heightened alert for a while.
Years ago I knew a guy who had been a deputy sheriff in Florida (years before that).
He said that when an unusual suicide got coverage in the newspaper and on TV (like somebody jumping off a building), it seemed like there was an increase in the number of suicides over the next few days.
He had no statistics but said that was his observation.
